If these tricks can hold up at swimsuit shoots on the beach, then they'll do the job for you, too!

You'll also be amazed at the time you'll save on styling with the two-minute updo and five-minute blowout secrets David shares.

Read on for these life hacks.

1. You could pull out your curling wand and take 30 minutes creating that undone, air-dryed, woke-up-like-this beach-hair look or not.

David recommends using a texturizing product on damp hair. Split hair in half, and roll each section away from the face. Blast the twist with the blow dryer.

The finished effect is perfectly undone waves with just enough volume. This technique also creates volume in limp, straight hair. You can also use this method to smooth unruly natural waves.

2. For static and unruly strands that won't calm down, a kabuki brush does the trick. Spritz a makeup brush, one that you won't be using on your face again, with hair spray. Then, use the densely packed hairs to smooth away flyaway hairs.

You'll get a sleek and smooth finish without that shiny, lacquered look.

3. Sometimes you want to put your hair up for a quick moment to keep hair out of your face or off your neck. But a hair elastic can leave that awkward bend in your blowout. Avoid that crease altogether by using your own strands as a hair tie.

Gather two small sections of hair right behind the ears and knot around your pony. Stick in one bobby pin at the base to keep the style from unraveling. Then when you're ready to rock your waves again, you can easily loosen the knot.

4. Sideswept bangs have the tendency to fall in your eyes and in the way. David's secret to keeping bangs over to the side requires just a little teasing at the roots. Use a rattail comb to backcomb the roots of the bangs in the direction you want them to fall. Then, smooth over any flyaways on top.

In addition to keeping your bangs in place, this teasing technique also helps create volume, so your bangs look full, not piecey.

5. Updos don't have to be complicated! David showed us a two-step hairstyle you can literally pull off in two minutes. Start by splitting your hair into two equal sections, and then wind your strands into a thick twist.

Roll up the twist to form a doughnut shape at the nape of your neck. Pin up the twist with bobby pins at the top, at the bottom, and on both sides. Carefully pull style to thicken the bun.

This glamorous chignon is perfect for gym-to-work or work-to-drinks. No one will know this style only took you two minutes and a few bobby pins.
